How Often Should You Really Change Your Engine Oil?

Thu, 30 Apr 2026 11:45:02 GMT

Oil change intervals used to be simple. Every 3,000 miles was the standard advice, and most drivers followed it without thinking twice. Modern engines, synthetic oils, and longer service intervals have changed that rule, but not always in ways that are easy to understand.

Many drivers now stretch oil changes based on guesswork, reminders, or what seems convenient. The real answer depends on how your vehicle is built and how you actually use it day to day.

Why Oil Changes Still Matter More Than People Think

Engine oil does more than lubricate moving parts. It helps manage heat, reduce friction, and carry away contaminants that build up during normal operation. Over time, that oil breaks down and loses its ability to do those jobs effectively.

Once oil starts degrading, internal wear increases. The engine may still run fine for a while, which is why delays are common. The damage, though, builds quietly in the background.

What Modern Oil Change Intervals Really Mean

Many newer vehicles can go 5,000 to 10,000 miles between oil changes, especially when using full synthetic oil. That does not mean every driver should aim for the maximum interval.

Driving conditions play a big role. Short trips, stop-and-go traffic, towing, and extreme temperatures all put more stress on the oil. In those cases, changing oil closer to the lower end of the interval makes more sense.

How Driving Habits Affect Oil Life

Not all miles are equal. Highway driving at steady speeds is easier on engine oil than frequent short trips where the engine never fully warms up. Cold starts, idling, and heavy loads all accelerate oil breakdown.

If your driving routine includes many short trips or city driving, your oil may need to be changed more frequently than the standard recommendation. That is where a more realistic schedule becomes important.

The Role Of Synthetic Oil In Longer Intervals

Synthetic oil is designed to last longer and perform better under heat and stress. That is why many manufacturers recommend it for modern engines. It holds its viscosity better and resists breakdown longer than conventional oil.

Even so, synthetic oil is not permanent. It still collects contaminants and eventually loses effectiveness. Extending oil changes too far, even with synthetic oil, can lead to sludge buildup and reduced protection.

Oil Life Monitoring Systems Are Helpful, But Not Perfect

Many vehicles now use oil life monitoring systems that track driving conditions and estimate when service is needed. These systems are helpful, but they are still based on programmed calculations rather than direct measurement of oil condition.

They are a guide, not a guarantee. If your driving conditions are more demanding than average, it is still a good idea to stay conservative with oil changes instead of relying entirely on the system.

Signs You Should Not Delay An Oil Change

Sometimes the vehicle gives clear signs that oil service should not wait. These include darker, thicker oil, engine noise, reduced performance, or a burning smell.

Even without obvious symptoms, sticking to a consistent schedule is the safest approach. Waiting for noticeable problems usually means the oil has already lost much of its protective ability.

Why Consistency Matters More Than Maximum Interval

The biggest mistake many drivers make is trying to stretch oil changes as far as possible. Saving one service interval may not seem like a big deal, but over time, that habit can lead to increased wear and more expensive repairs.

Regular maintenance keeps the engine cleaner and helps avoid long-term damage. A consistent oil change schedule is more important than pushing for the longest possible interval .

When It Makes Sense To Change Oil Sooner

If you are unsure about your driving conditions or the condition of your oil, it is better to err on the side of caution. Changing oil a little sooner is far less costly than dealing with engine wear later.

Vehicles with higher mileage, turbocharged engines, or frequent stop-and-go use benefit from shorter intervals. An inspection during service can also help determine if adjustments are needed.

What Is Causing That Whining Noise From Under the Hood?

Fri, 27 Mar 2026 14:00:36 GMT

A whining noise from under the hood usually gets louder in your mind every time you drive. It may start as a faint sound at startup, then become easier to hear when you accelerate, turn the wheel, or let the engine idle in a parking space. Some drivers notice it right away. Others hear it for a few days before realizing it is happening on every trip.

That kind of sound usually means one moving part is no longer turning as cleanly as it should.

Why A Whining Noise Should Not Be Ignored

Whining noises usually come from parts that spin, build pressure, or rely on bearings to keep friction low. When one of those parts starts wearing out, the sound is often your earliest warning. The vehicle may still drive fine for now, though the noise is telling you that extra strain is building under the hood.

That is why a quick inspection is a better move than turning the radio up and hoping the sound fades away. A whining noise rarely disappears for a good reason. In most cases, it grows louder as the affected part wears further or starts putting extra load on nearby components.

The Sound Often Changes With Engine Speed

One of the most useful clues is whether the whining rises and falls with engine RPM. If the sound gets sharper when you press the gas, that usually points toward a belt-driven component or something attached to the engine itself. If it is strongest at idle and fades slightly as you move, that can point in a different direction.

The way the sound changes during turns helps too. A whine that gets louder while turning the steering wheel often points toward the power steering system on hydraulic setups. A noise that grows stronger when the air conditioning is switched on can shift attention toward the compressor or belt load. Small patterns like these help narrow the problem down much faster.

Common Sources Of A Whining Noise

A few parts show up again and again when drivers describe a whine from under the hood.

A worn serpentine belt that is slipping under load
A tensioner or idler pulley with a failing bearing
A power steering pump running low on fluid or wearing out
An alternator bearing is starting to fail
An air conditioning compressor or clutch is making noise
A vacuum leak creates a high-pitched whistling sound

Each one creates a slightly different tone, though they can sound similar from the driver’s seat. That is why the source has to be confirmed instead of being guessed.

Belts And Pulleys Are Frequent Culprits

The serpentine belt runs several major accessories, so any problem in that system can create noise quickly. A worn belt may start slipping and produce a high-pitched whine or squeal, especially during startup or when extra load is placed on the engine. If the belt is glazed, cracked, or contaminated with oil or coolant , the sound often worsens.

Pulleys are just as important. A weak tensioner or failing idler pulley bearing will create a steady mechanical whine that changes with engine speed. We see this quite a bit on higher-mileage vehicles where the belt was replaced once, though the pulleys were left in place and kept aging.

Power Steering And Charging Problems Have Their Own Sound

On vehicles with hydraulic power steering, a low fluid level or a worn pump creates a very recognizable whine. The noise usually gets louder when you turn the wheel at low speed, because that is when the system is working hardest. If the reservoir is low, there is usually a leak somewhere in the system that needs to be found.

Charging system problems can sound similar. An alternator with a worn bearing often produces a smooth , rising whine that closely follows engine speed. In some cases, dimming lights or a battery warning light show up later. In others, the sound is the first clue that the alternator is starting to wear internally.

When The Noise Means A Bearing Is Wearing Out

A lot of under-hood whining comes down to bearings. Alternators, pulleys, water pumps, and compressors all rely on bearings to spin freely. Once a bearing starts drying out or wearing down, friction increases, and the sound becomes more noticeable over time.

This is one reason the noise should be checked early. A bearing that is only noisy today may seize later, throw the belt off, or damage the accessory it supports. During regular maintenance, these problems are often easier to catch before the noise turns into a breakdown.

Why Early Testing Saves Money

Whining noises are usually easier to pinpoint when they first start. The sound pattern is cleaner, the affected part has not damaged surrounding components, and the repair tends to stay focused. Waiting too long often leads to belt damage, fluid loss, overheating, charging trouble, or a vehicle that suddenly becomes undrivable.

A proper check should include belt condition, pulley operation, fluid levels, bearing noise, and accessory load. That full inspection gives a much clearer answer than replacing parts based on guesswork. Once the source is confirmed, the repair is usually far more straightforward.

What Happens When You Skip An EV Coolant Flush, and How Does It Differ From an Engine Coolant Flush?

Fri, 27 Feb 2026 15:45:13 GMT

EV owners hear coolant and think of the engine, but the job is still the same at its core: move heat away from expensive parts so they stay in their safe temperature range. The difference is that an EV uses coolant to protect the battery and power electronics, and sometimes to support cabin heating, not a combustion engine block. When coolant service gets skipped, the car may keep driving fine for a while, then start limiting charging or power when you need it most.

Thermal control is the reason modern EVs feel consistent.

How EV Cooling Systems Really Work

Most EVs have one or more coolant loops that circulate through a battery pack and the power electronics, then dump heat through a radiator or a dedicated heat exchanger. Electric pumps and valves manage flow depending on conditions, and the vehicle monitors temperatures constantly. If the system cannot shed heat effectively, the car protects itself by reducing fast charging speed or limiting power output.

Some EVs also tie cooling into cabin comfort through a heat pump or chiller strategy. That means coolant conditions can influence more than one system, even if everything sounds normal from the driver’s seat.

What Skipping An EV Coolant Flush Can Lead To

Coolant is not permanent. Over time, corrosion inhibitors get used up, the pH can shift, and small amounts of debris can build up in the system. That reduces heat transfer and can restrict flow through narrow passages in heat exchangers, which makes pumps work harder, and temperatures climb faster under load.

When EV temperatures rise outside their targets, the car often activates protection modes rather than immediately breaking down. You might notice reduced charging speed, limited power during long climbs, or fans running longer after you park. Left alone long enough, poor coolant condition can contribute to pump wear, leaks at seals, and internal corrosion that is far more expensive than a scheduled service.

EV Coolant Flush Versus Engine Coolant Flush

An engine coolant flush is built around combustion heat and very high temperature cycling . The coolant must manage hot spots, pressure changes, and the risk of contamination from internal leaks. On many gas vehicles, the service also involves checking thermostat operation, radiator flow, and heater core performance, because all of it is tied to the same loop.

EV coolant service is more about stable thermal management and keeping conductivity, corrosion protection, and flow where the manufacturer expects. Some EVs have multiple loops that require specific bleeding or vacuum-fill procedures, and mixing coolants or using the wrong spec can create problems quickly. The service is not complicated for a trained shop, but it is less forgiving of shortcuts than people assume.

Intervals And Why Some EVs Need It Sooner

Most manufacturers publish a time and mileage interval, and that is the best starting point. If the vehicle sees frequent fast charging, heavy hill driving, towing, or hot-weather commuting, the thermal system works harder and the coolant ages under greater heat load . Short trips also matter because systems cycle on and off more often, which stresses seals and can reveal small leaks sooner.

This is one of those services that fits naturally into regular maintenance because you are preserving temperature control instead of waiting for a warning. The goal is to keep coolant chemistry and flow stable so the car behaves the same in summer traffic as it does on a mild day.

Signs Your EV Cooling System Needs Attention

A few patterns tend to show up when coolant level, flow, or heat exchange is not where it should be. Watch for changes that repeat, not one-off weirdness.

Fast charging slows down more than normal in similar conditions
Power feels limited during long climbs or highway pulls
Cooling fans run loudly or longer than usual after shutdown
Cabin heat or A/C performance changes along with temperature messages
You smell a sweet odor near the front of the vehicle after driving
Low coolant level returns after topping off

If you notice these, avoid topping off repeatedly and calling it solved. Coolant does not disappear without a reason, and adding the wrong fluid can create a bigger mess than the original leak.

Why Coolant Type And Fill Procedure Matter

EV cooling components have tight passages and sensitive materials, so coolant spec matters. Mixing incompatible types can cause gelling or sludge, and using tap water can introduce minerals that do not belong in a modern cooling system. The right fluid, in the correct concentration, is what keeps heat transfer predictable and helps seals live a long time.

Air pockets are another issue. Trapped air can create hot spots, noisy pumps, and temperature swings that lead to repeated warnings. A proper inspection confirms the correct fill level, checks for leaks and pressure stability, and verifies the system can circulate and reject heat the way it was designed to.

Why Do My Car Brakes Squeak In The Morning?

Fri, 30 Jan 2026 14:15:07 GMT

Morning brake squeaks can be irritating, especially when the car feels fine the rest of the day. You back out, tap the brakes, and the noise shows up like it has a schedule.

The good news is that morning squeaks are often explainable, and they are not always a sign that something is failing. Below are the most common reasons it happens, plus the signs that suggest it’s time to take the noise more seriously.

Why Morning Brake Squeaks Are So Common

Brakes are exposed to air, moisture, and road film every time you drive. Overnight, those conditions change. Temperatures drop, humidity rises, and condensation can settle on metal surfaces. By morning, the first few stops can sound different even if nothing has “broken” since yesterday.

Cold also changes the way materials behave. Brake pads, rotors, and even small clips and shims can be a little noisier until they warm up and settle into their normal operating feel.

Condensation And Light Surface Rust Overnight

One of the most common reasons for morning squeaks is a thin layer of surface rust on the rotors. It can form in a single night, especially in damp weather or after a rainy drive. The first few brake applications scrape that film off, which can create a squeak, a light scraping sound, or a brief rough feel in the pedal.

This is usually short-lived. After a few stops, the rotor surface cleans up and the noise fades. If the noise disappears consistently once you’ve been driving for a bit, light rust film is a strong possibility.

Pad Material And Cold Brakes Can Be Noisy

Different pad materials make different noises, and many pads are naturally noisier when cold. Some compounds are designed to handle heat well, and they can be a little louder during the first few stops. That can show up as a squeak that seems worse early in the day, then settles down as the brakes warm up.

Dust can contribute too. Fine brake dust builds up on pad edges and rotor surfaces. Overnight moisture can mix with that dust and create a slightly grabby surface that squeaks until it clears.

We’ve seen plenty of vehicles where the brakes measure fine and stop well, but the pad compound simply talks back during cold, damp mornings.

Brake Hardware Issues That Make Noise At Low Speed

If the squeak is sharp and repeatable, especially at very low speeds, hardware is worth considering. Brake pads are held in place with clips, shims, and slide points that keep everything aligned. When those parts are worn, dirty, or dry, the pads can vibrate slightly during braking, and that vibration becomes a squeak.

Caliper slide pins are another common factor. If the slides are sticking, the pad may not release cleanly, and you can get noise during the first few stops. In some cases, the noise comes with a faint drag feel, or one wheel seems to collect more brake dust than the others.

Driving Conditions That Make Morning Squeaks More Likely

Some routines make the brake noise show up more often , even when the brakes are in decent shape. This is less about doing something wrong and more about what the brakes go through.

Parking outside where humidity and dew settle on rotors overnight
Short trips where brakes do not heat up much during the day
Frequent stop-and-go driving that builds dust quickly
Washing the car or driving through puddles late in the day, then parking

If your vehicle fits one or two of these, a brief morning squeak is not unusual.

When Morning Squeaks Suggest A Real Brake Problem

Some brake noises are normal. Others are warnings. The difference is whether the sound is changing, sticking around, or paired with other symptoms.

Look at the overall pattern, not just the fact that there is a squeak. These signs deserve attention sooner rather than later:

The squeak lasts all day, not just the first few stops
The noise is getting louder or more frequent week to week
You feel vibration in the brake pedal or steering wheel while braking
The vehicle pulls to one side when braking
You hear grinding, or braking distance feels longer than it used to

If any of those are happening, it’s smart to have the brakes checked before the wear reaches the point where rotors or calipers get damaged.

Keeping Morning Brake Noise From Becoming A Repeat Problem

If the cause is light surface rust, the fix might be as simple as confirming the pad and rotor condition and making sure everything is wearing evenly. If hardware is the culprit, replacing worn clips, servicing slide pins, and correcting pad fitment can make a noticeable difference.

If pads are near the end of their life, replacing them sooner can prevent the squeak from turning into grinding. It can also protect the rotors from scoring. The goal is to keep the braking feel consistent and predictable, not to chase noise forever.

How to Tell If You Have a Clogged Heater Core

Fri, 19 Dec 2025 15:30:11 GMT

When the weather turns cold, and you turn the heat on, you expect warm air within a minute or two. If you get lukewarm air, weak airflow out of the vents, or a sweet smell in the cabin instead, your heater core may be trying to tell you something. A clogged heater core will not fix itself, and leaving it alone can create bigger problems than just a chilly ride.

What The Heater Core Does For Your Cabin

The heater core is basically a small radiator tucked inside the dashboard. Hot engine coolant flows through its tiny passages, and the blower motor pushes air across it, sending heat into the cabin. When coolant moves freely through the core, you get steady, reliable heat and a clear windshield from the defrost mode.

If those passages start to clog with rust, scale, or debris, less hot coolant can flow through. The blower is still pushing air, but it is not picking up much heat, so the vents feel cool or only slightly warm. That is usually the first way a heater core problem shows up for most drivers.

Early Signs Your Heater Core Is Starting To Clog

A heater core rarely goes from “perfect” to “completely blocked” overnight. Most of the time you will notice little changes first, such as:

Heat that takes much longer than usual to show up after a cold start
Vents that blow warm air when you are driving but cooler air at idle
Temperature that changes as you rev the engine, hotter when the RPMs are higher
One side of the cabin feels warmer than the other on dual zone systems

Those symptoms can point to coolant flow problems through the core . Our technicians listen closely to when the heat cuts out or comes back, because that timing helps separate a heater core issue from blend door or thermostat problems.

Smells, Fog, And Leaks: When A Clog Affects Coolant

As a heater core ages, clogging and internal leaks sometimes show up together. If the core starts to seep, you may notice a sweet, coolant-like smell inside the cabin, especially when the heat or defrost is on. The inside of the windshield can fog up quickly and may leave a slightly greasy film that is hard to wipe away.

In more advanced cases, you might see damp carpet on the passenger side or a small puddle under the dash. The coolant level in the reservoir will usually drop over time, even if you never see a leak under the vehicle. At that stage, the heater core is not just clogged; it is allowing coolant to escape where it does not belong.

How A Clogged Heater Core Can Hurt Your Engine

It is easy to think of the heater as a comfort feature, but it is tied directly into the cooling system. A badly restricted heater core can affect how coolant flows through the rest of the system and may contribute to higher engine temperatures. If air gets trapped in the core or hoses, that air pocket can interfere with proper circulation.

On some vehicles, a clogged heater core is one of several signs that the coolant has been neglected for too long. Rust and debris that plug the small passages in the core often come from the larger cooling system. If we see a blocked core and very dirty coolant, we know it is time to look at the bigger picture to protect the engine, not just the dash components.

Driver Habits That Speed Up Heater Core Problems

Some everyday choices and long term habits can make heater core issues more likely:

Skipping coolant changes for years , which lets corrosion build up inside small passages
Topping off with plain water instead of the correct coolant mix
Ignoring small leaks or low coolant levels and just adding more fluid now and then
Mixing several different coolant types together without checking compatibility

We have worked on vehicles where the heater core was essentially packed with sludge because the coolant had never been serviced. A little attention to coolant quality and the correct type goes a long way toward keeping the core open.

What You Can Safely Check At Home

You do not have to pull the dashboard apart to gather useful clues. A few simple checks at home can help:

With the engine completely cool, verify the coolant level in the reservoir is at the proper mark
Turn the heat to full hot and feel how quickly and how strongly warm air comes out as you drive and as you idle
Watch the temperature gauge on a typical drive; note whether it behaves normally or swings around
Look for damp carpet on the passenger side and any foggy film on the inside of the windshield

If you notice low coolant, strong coolant smells, or repeated fogging, it is best to have the system inspected rather than just topping off and hoping it goes away.

How Technicians Diagnose A Clogged Heater Core

In the shop, we start by confirming coolant level and condition, then check the heater hoses going into the firewall. On a warmed-up engine, one very hot hose and one much cooler hose can indicate restricted flow through the core. We also verify that blend doors and controls are actually sending air through the heater core, not bypassing it.

Depending on what we find, the solution might be a careful cooling system service and heater core flush, or it might require replacing the heater core if it is leaking or severely blocked. We look at the whole system, because fixing only the symptom inside the dash without addressing dirty coolant or leaks elsewhere usually means the problem will come back.

Get Heater Core Repair in Lakewood, WA with Tveten's Auto Clinic

If your heater has gone weak, your windshield keeps fogging up, or you notice a coolant smell inside the cabin, your heater core may need attention. We can inspect your cooling system, test heater core flow, and recommend the right repair to bring your heat and defrost back.

What Are The 5 Most Important Car Filters And When to Replace Them

Fri, 28 Nov 2025 14:45:03 GMT

Filters do quite a work that keeps engines running clean, cabins comfortable, and transmissions alive. When they clog, you feel it in sluggish response, poor fuel economy, and strange noises. Here in Lakewood, our technicians see the same five filters over and over, and staying ahead of them saves bigger repairs later.

1. Engine Oil Filter

Your oil filter traps metal flakes, soot, and varnish so clean oil can protect bearings and cam surfaces. When it loads up, the bypass valve can open and send unfiltered oil through the engine. That is when wear accelerates. Most cars do well with replacement at every oil change. If you tow, drive lots of short trips, or run a turbo engine, keep intervals tight. We match the filter to the engine’s spec and check for a clean anti-drainback valve to prevent noisy starts after the car sits overnight.

2. Engine Air Filter

The engine air filter keeps dust and grit out of the intake. A clogged filter restricts airflow, which can dull throttle response and raise fuel trims . In our region, a long summer of road dust or a few fall trips down gravel can load a filter quickly. We inspect it at every service, looking for dark, caked pleats or debris in the airbox. Most drivers see replacement every 15,000 to 30,000 miles, sooner if you travel unpaved roads or commute through construction zones.

3. Cabin Air Filter

This one protects you and the HVAC system. The cabin filter catches pollen, dust, and road soot before air passes the heater core and evaporator. When it clogs, you get weak airflow, slow defrost, and a blower that sounds like it is working too hard. If the inside of the windshield fogs easily, a choked cabin filter may be part of the story . Plan on 12,000 to 20,000 miles, or once a year. We like to change it before the wet season, so defrost works fast on cold Lakewood mornings.

4. Fuel Filter

Clean fuel protects injectors and high-pressure pumps. Some vehicles have a serviceable inline filter, others use a filter built into the pump module in the tank. A restricted filter can show up as hard starts, hesitation on hills, or a loud, straining fuel pump. If your car has a serviceable filter, a 30,000 to 60,000 mile interval is common . For lifetime filters inside the tank, we monitor pressure and volume; if we see drop off or contamination in a fuel sample, we plan the correct repair rather than guessing at parts.

5. Transmission Filter

On transmissions with a real filter and pan, fluid carries clutch material and fine metal that the filter captures. When it loads up, shift quality suffers and heat climbs. Not every car has a replaceable filter, but if yours does, pan-drop service with a new filter is the right move. For many conventional automatics, 30,000 to 60,000 miles is a sensible window. We always verify the proper fluid spec, because the wrong fluid can create shudders and shorten the life of the unit.

How Often Should You Replace Filters?

Intervals are guidelines, not promises. Short trips, towing, mountain grades, and stop-and-go traffic all shorten service life. A simple rule helps: if you have changed driving habits or the car has started a new job, filters earn an earlier look. At our repair shop we check the air, cabin, and visible fuel filters during routine visits and document the condition with photos. For sealed systems, we use pressure and flow tests so you are not replacing parts on a hunch.

Winter Maintenance Checklist: What Your Car Needs Before the Holiday Trips

Fri, 31 Oct 2025 15:00:17 GMT

Before heading out on the road for holiday travel, it’s important to make sure your car is ready for winter conditions. Cold weather, icy roads, and long highway miles can push your vehicle harder than usual. A few preventive checks and services can go a long way in avoiding breakdowns or delays during one of the busiest driving seasons of the year.

Here’s a simple yet essential winter maintenance checklist to keep your car dependable and safe for holiday travel.

Inspect the Battery and Charging System

Car batteries lose strength in cold weather. If your battery is more than three years old, now is the time to have it tested. A weak battery can easily fail after a cold night , leaving you stranded when you need your car most.

In addition to checking the battery itself, have your alternator and charging system inspected to ensure everything is operating as it should. Clean any corrosion from the battery terminals and make sure the cables are tight.

Check Antifreeze and Cooling System Health

Your engine's cooling system protects it from both overheating and freezing. Make sure your coolant level is correct and the mixture is properly balanced. Antifreeze not only lowers the freezing point of the fluid but also protects against corrosion inside the engine.

A technician can test the condition of the coolant and flush the system if it’s dirty or past its service interval. This is a key step in preventing costly damage to your radiator, water pump, and other components.

Inspect the Tires and Tire Pressure

Good tires are critical for safe winter driving. Check the tread depth and look for signs of uneven wear or cracking. Tires with low tread are more likely to lose grip on wet, snowy, or icy roads.

Cold temperatures cause tire pressure to drop, so it’s also important to check and adjust the pressure regularly. Refer to the label inside your driver’s door for the recommended PSI.

Test the Heater and Defroster

You rely on your heater and defroster for comfort and visibility during winter drives. If either system isn’t working correctly, have it repaired before your trip. A weak defroster can make it difficult to see through a fogged windshield, especially during early mornings or rainy weather.

Top Off Fluids and Replace Windshield Wipers

Make sure all fluids are full, including engine oil, transmission fluid, brake fluid, and windshield washer fluid. In winter, it’s best to use washer fluid formulated to prevent freezing.

Also, replace worn or streaking windshield wipers with a winter-grade set. Visibility is critical during snow and rain, and fresh wipers can make a big difference.

Inspect Belts and Hoses

Cold weather can make rubber components brittle and more likely to crack. Have your technician inspect the serpentine belt and all coolant hoses for signs of wear, fraying, or leaks. If any part looks worn or aged, replacing it now can prevent a breakdown later .

Check Lights and Brakes

Make sure all your exterior lights are working properly, including headlights, brake lights, and turn signals. With fewer daylight hours in winter, visibility becomes even more important.

You should also have your brake system inspected. Good brakes are essential for stopping safely on slippery roads. Listen for squealing or grinding sounds and have your pads and rotors checked if you notice anything unusual.

Pack an Emergency Kit

Even with good preparation, winter travel can bring surprises. An emergency kit with items like jumper cables, a flashlight, warm blankets, gloves, water, and basic tools can be a lifesaver if you get stuck or stranded. A portable phone charger or power bank is also helpful in case your phone battery runs low.

What Are The Most Overlooked Maintenance Tasks Drivers Forget About Before the Cold Weather Hits?

Fri, 26 Sep 2025 14:45:05 GMT

When temperatures begin to drop in Lakewood, most drivers focus on obvious winter prep like antifreeze, tires, or battery checks. But while those are essential, many other important maintenance tasks tend to be forgotten. Overlooking them can lead to unexpected breakdowns, poor performance, and costly repairs once the cold weather settles in.

Let’s take a look at some of the most commonly ignored maintenance tasks that can quietly turn into big problems if skipped during your winter prep.

Cabin Air Filter Replacement

A lot of drivers don’t think about the cabin air filter until the air starts smelling musty or the vents seem weak. In colder months, a clogged cabin air filter makes it harder for your heating and defrost systems to keep the windows clear and the cabin comfortable. The filter catches dust, pollen, leaves, and even mold spores. Over time, it restricts airflow and creates unpleasant odors, especially if it’s been exposed to moisture.

Replacing the cabin air filter is a quick, affordable task that can make a huge difference in comfort and visibility during cold, damp mornings.

Headlight and Taillight Inspection

Shorter days and longer nights mean you’ll rely on your vehicle’s lighting more than usual. But many drivers don’t notice when a headlight, brake light, or turn signal burns out until someone points it out. Dim or non-functioning lights reduce your visibility and make your vehicle less noticeable to others on the road.

As part of your winter prep, walk around your vehicle and inspect all exterior lights. If any bulbs are out or fogged over, replace them. Clean the headlight lenses too, as cloudy covers can drastically cut light output in dark or foggy conditions.

Washer Nozzle and Hose Check

You might top off your washer fluid and assume the system is good to go, but what if the nozzles are blocked or the hoses are cracked? If water can’t spray properly, your windshield will quickly become a visibility hazard on slushy, salty roads.

Washer nozzles often get clogged with dirt or frozen water, and old hoses can become brittle and crack during the first deep freeze. Make sure the system works properly by testing it before the weather turns severe.

Heater and Defroster Function Test

Many drivers don’t find out their heater isn’t working until it’s already freezing outside. HVAC issues can sneak up slowly, like weak airflow or delayed heating. If your defrosters take too long to clear the windshield or the rear defroster grid doesn’t seem to work, your view can quickly become compromised.

Check both the front and rear defrosters early in the season. If the air doesn’t feel warm or the fans don’t blow consistently, it’s worth having a technician take a closer look before the cold sets in.

Windshield Wiper Arm Pressure

Most people remember to replace old or streaky wiper blades, but the arms themselves can also be a problem. Over time, wiper arms lose tension and may not press the blade firmly against the glass. This results in uneven wiping or missed spots right when you need clear vision the most.

Inspect the arms to ensure they’re making solid contact with the windshield. If they seem loose or if the blade lifts away at highway speeds, it might be time to replace the arms or have them adjusted.

Tire Rotation and Alignment

Drivers often check tire pressure before winter, but rotation and alignment are just as important. Uneven tire wear affects how well your vehicle grips the road, especially on slick surfaces. Alignment issues can also cause your vehicle to drift, making it harder to control in snow or ice.

Rotating the tires before the season changes ensures even wear and helps your tires last longer. If your vehicle pulls to one side or the steering wheel vibrates at speed, a quick alignment check can prevent bigger problems during winter travel.

Battery Cable Condition

While battery testing is common before winter , not everyone checks the cables and terminals. Corrosion or frayed wires can limit power flow even if the battery itself is fine. Cold weather requires more current to start your engine, so any weak connection can lead to a no-start situation on a frosty morning.

Look for white or green buildup around the terminals and make sure the cables are tightly secured. If you see cracking in the cable insulation, it’s time for a replacement.

September Brake Check Tips for End-of-Summer Drives

Fri, 29 Aug 2025 13:00:40 GMT

As summer comes to an end, many drivers are still squeezing in weekend getaways, last-minute road trips, and visits to see friends and family. Whether you’ve spent the season cruising the highway or making frequent local trips, your brakes have been working hard. September is the perfect time to give them a thorough check so you can head into the fall driving season with confidence and safety.

Why a Brake Check in September Is a Smart Move

By the end of summer, brakes often have more wear than you realize. Heat, heavy traffic, and long drives can all take a toll. Scheduling a brake inspection before the weather turns wet and roads become slick ensures that your stopping power is at its best when you need it most.

Signs Your Brakes Need Attention

Your car may give you several warnings when the brakes are wearing down or malfunctioning. Some of the most common signs include:

Squealing or squeaking noises when applying the brakes
Grinding sounds, which may mean the pads are worn down to metal
A soft or spongy brake pedal
Vibrations or pulsations in the steering wheel when braking
The vehicle pulling to one side during stops

Even if you don’t notice these symptoms, it’s worth having your brakes inspected regularly to catch problems before they worsen.

The Impact of Heat on Brake Performance

During summer, high temperatures and stop-and-go driving can cause brake components to heat up more than usual. Excessive heat can glaze brake pads, reducing their ability to grip, and can also warp rotors. Once warped, rotors may cause vibration and uneven braking, making it harder to stop quickly and safely.

Key Components to Check in a Brake Inspection

A proper brake inspection goes beyond just looking at the pads. Technicians will also:

Measure rotor thickness and check for warping
Inspect calipers for leaks or sticking pistons
Check brake fluid level and condition
Examine brake lines for cracks, corrosion, or leaks
Test the parking brake for proper function

Addressing even small issues early can prevent more expensive repairs later.

Brake Fluid: Often Overlooked but Essential

Brake fluid is vital for transmitting the pressure from your foot on the pedal to the brake components at each wheel. Over time, it can absorb moisture, which reduces its effectiveness and can cause corrosion in the system. Many manufacturers recommend replacing brake fluid every two to three years, and a September inspection is a great time to see if yours needs changing.

Preparing for Fall and Winter Driving Conditions

In Lakewood, fall often means rain and slick roads, and winter brings its own challenges. Well-maintained brakes give you the stopping power needed to navigate wet intersections, sudden stops, and potential hazards. By checking your brakes in September, you’re getting ahead of seasonal hazards instead of dealing with them when conditions are already poor.

Extend Brake Life with Smart Driving Habits

You can help your brakes last longer by avoiding sudden stops, coasting to slow down when possible, and keeping a safe following distance. Avoid riding the brakes on long downhill stretches—downshifting when appropriate can help reduce wear. Regular inspections also ensure that small problems don’t escalate into costly repairs.

Schedule Your Brake Service Before the Rush

At Tveten’s Auto Clinic in Lakewood, WA, we recommend scheduling your brake inspection in September so you’re ready for the fall driving season. Our technicians will check every part of your braking system, from pads and rotors to fluid and calipers, making sure your car stops as it should.

Book your appointment today and enjoy the peace of mind that comes with reliable brakes for every drive.

How Can I Tell If My Battery Is Dying?

Fri, 25 Jul 2025 13:30:14 GMT

Your car battery is one of those parts you might not think about until the moment it fails — usually at the worst possible time. It’s responsible for providing the power needed to start your engine and run all electrical systems when the car isn’t running. Recognizing the warning signs of a dying battery can help you avoid the inconvenience of being stranded and prevent additional strain on other vehicle components.

The Role of Your Car Battery

A car battery stores electrical energy and delivers it to the starter motor and ignition system when you turn the key. It also powers accessories like lights, radio, and climate controls when the engine is off. Once the engine starts, the alternator takes over to keep everything running and to recharge the battery for the next start.

Batteries typically last between three and five years, but their lifespan depends on factors such as driving habits, climate, and the level of vehicle maintenance.

Difficulty Starting the Engine

One of the first and most common signs of a dying battery is trouble starting your car. You may notice that the engine cranks more slowly than usual or requires multiple attempts before it starts. This happens because the battery no longer has enough charge to power the starter motor effectively.

On colder mornings, these symptoms might be even more pronounced since batteries lose capacity in low temperatures.

Dim or Flickering Lights

Your headlights and interior lights rely directly on battery power when the engine is off and on the charging system when running. If your headlights appear dimmer than usual or flicker when idling, this may indicate the battery is struggling to supply consistent voltage.

Dimming lights can also suggest a problem with the alternator, so it’s important to get it checked professionally to confirm the cause.

Electrical Component Malfunctions

Modern vehicles feature numerous electrical systems, including power windows, heated seats, and infotainment screens. If you notice sluggish or inconsistent performance from these systems — such as windows moving slower or dashboard lights fading — your battery might be to blame.

A weak battery can’t maintain the necessary voltage, leading to erratic or weak operation of these systems.

Dashboard Warning Light

Most cars are equipped with a battery warning light on the dashboard. While this light can indicate alternator problems , it may also signal that the battery isn’t holding a proper charge. If this light turns on, it’s a clear sign that you should have your charging system inspected as soon as possible.

Corrosion Around Battery Terminals

Physical signs of battery trouble can include corrosion around the terminals. Corrosion appears as a white, ashy substance on the metal parts where the battery cables connect.

This buildup can interfere with the connection, making it harder for the battery to deliver power and causing voltage drops. Cleaning corrosion carefully can sometimes help, but persistent buildup usually indicates an aging battery.

Swollen Battery Case

A swollen or bloated battery case is another sign that your battery is failing. Excessive heat or internal failure can cause the battery case to expand. A swollen battery is not just a sign of a problem; it can be dangerous and should be replaced immediately.

Frequent Jump-Starts

If you find yourself needing jump-starts more often, it's a strong indication that your battery can no longer hold a charge. While jump-starting can get you moving temporarily, repeated reliance on it is a sign that replacement is necessary.

Why Timely Replacement Matters

Delaying battery replacement can leave you stranded at an inconvenient or even unsafe moment. Additionally, a weak battery can overwork the alternator as it tries to keep the battery charged, potentially leading to alternator failure, an expensive repair.

Regular Battery Checks

Routine battery checks, especially before winter or long trips, can save you from unexpected failures. A professional can test your battery’s charge capacity, inspect the condition of the terminals, and evaluate the entire charging system to catch potential issues early.

Why Does My Car Idle Rough When It’s Hot?

Thu, 19 Jun 2025 13:04:57 GMT

When your car is cold, a slightly rough idle may seem normal. But if the engine continues to idle poorly or even worsens once it’s warm, something isn’t right. A rough idle after warming up could mean your engine is misfiring, running too lean or rich, or struggling with airflow. These issues not only affect comfort while driving but can also hurt fuel economy, emissions, and long-term engine health.

If your car shakes at stoplights idle inconsistently or sounds different when it's hot, don’t ignore it. Getting to the bottom of a rough idle early can prevent expensive repairs down the line.

What Is a Rough Idle

A rough idle means your engine doesn’t run smoothly while idling—typically when your foot is off the gas, and the vehicle is at rest. The engine might shake, sputter, or change RPMs unexpectedly. Sometimes, the check engine light comes on, but not always. What makes this frustrating is that the symptoms can appear only after the engine reaches its normal operating temperature, which can make diagnosis tricky.

Common Causes of Rough Idle When Warm

Several issues can cause a rough idle once the engine is fully warmed up. Here are some of the most likely culprits:

Vacuum Leaks

As the engine warms up, rubber hoses expand, and small vacuum leaks can become more noticeable. A vacuum leak allows unmetered air into the engine, which disrupts the air-fuel mixture. The result is an unstable idle, often accompanied by a high-pitched hissing sound under the hood.

Dirty or Failing Mass Airflow Sensor (MAF)

The MAF sensor monitors the amount of air entering the engine. If it's dirty or faulty, the engine control module can miscalculate how much fuel is needed. This leads to inconsistent engine behavior, especially once the sensor has warmed up and its readings become more erratic.

Faulty Idle Air Control Valve (IAC)

This component controls how much air enters the engine at idle. Over time, it can become clogged with carbon deposits or start to fail. A malfunctioning IAC valve can cause rough or fluctuating idle, especially once the engine warms and the ECU reduces cold-start adjustments.

EGR Valve Problems

The Exhaust Gas Recirculation (EGR) valve helps reduce emissions by recirculating a small amount of exhaust gas back into the combustion chamber. If the valve sticks open, it can cause a rough idle, particularly when the engine is hot.

Leaky Fuel Injectors

A fuel injector that leaks or sprays unevenly may not be noticeable during cold starts but can begin to cause misfires and a rough idle as the engine heats up . You may also notice a drop in fuel efficiency or a gas smell near the engine.

Worn Spark Plugs or Ignition Coils

Heat can reveal electrical problems that don’t show up when the engine is cold. Failing spark plugs or ignition coils can misfire only when hot, creating a rough idle or stalling condition. A scan for trouble codes often reveals which cylinder is affected.

Other Signs to Watch For

A rough idle rarely comes alone. You may also notice other symptoms, such as:

Reduced fuel economy
Loss of power or hesitation when accelerating
Strong exhaust smell
Check engine light
Engine stalling at stops

These additional clues can help a technician zero in on the issue during a diagnostic inspection .

The Importance of Timely Diagnostics

When your engine starts running rough, it’s not something to wait on. The longer the issue goes unresolved, the greater the risk of secondary damage. For example, misfires can damage your catalytic converter over time, and vacuum leaks can stress the engine control systems trying to compensate.

Technicians use scan tools, smoke machines, and pressure tests to pinpoint the problem quickly. In many cases, the repair might be as simple as cleaning a sensor or replacing a worn ignition component.

How Often Should I Change My Car’s Transmission Fluid?

Fri, 30 May 2025 15:15:18 GMT

Transmission fluid keeps your car’s transmission cool, clean, and functioning smoothly. But unlike oil changes, which are done regularly, many drivers aren’t sure when, or even if, their transmission fluid needs to be replaced. Waiting too long can lead to expensive repairs, so understanding the right timing for fluid changes is essential.

Check the Manufacturer’s Recommendation First

The best place to start is always your owner’s manual. Most manufacturers provide a specific mileage or time interval for when to change the transmission fluid. For many vehicles, it’s somewhere between 30,000 and 60,000 miles, but for newer models with advanced transmission systems, it could be as high as 100,000 miles.

That said, these recommendations assume ideal driving conditions. If your vehicle sees a lot of stop-and-go traffic, towing, mountainous driving, or extreme weather, you may need to change the fluid more often than the manual suggests.

Signs Your Transmission Fluid Needs Changing

Even if you haven’t hit the mileage mark, your transmission might be telling you it needs attention. Warning signs include delayed shifting, hard gear changes, or slipping when accelerating. If the fluid looks dark, smells burnt, or feels gritty when checked, it’s time to replace it—even if you’re technically ahead of schedule.

Some vehicles have sealed transmissions without traditional dipsticks, which makes checking the fluid harder for the average driver. In these cases, a visit to a shop with the right tools is necessary to monitor fluid levels and condition.

Why Fresh Transmission Fluid Matters

Transmission fluid acts as both a lubricant and a coolant. Over time, it breaks down from heat and friction, losing its ability to protect internal components. Old or dirty fluid can’t effectively transfer power, leading to poor performance and increased wear.

Fresh fluid keeps the internal parts clean and properly lubricated, extending the life of the transmission. It also helps prevent overheating, one of the leading causes of transmission failure.

Automatic and Manual Transmissions Have Different Needs

While automatic transmissions rely heavily on fluid to operate, manual transmissions use it primarily for lubrication. That means fluid in a manual gearbox typically lasts longer, but still needs to be changed on schedule.

Vehicles with CVT (continuously variable transmission) or dual-clutch systems require specialized fluids and often have unique service intervals. Using the wrong type of fluid can damage the transmission, so it’s critical to use what’s specified by the manufacturer.

What Happens During a Transmission Fluid Service

A proper transmission service involves more than just draining and refilling the fluid. Depending on the vehicle, the service may include:

Replacing the transmission filter
Cleaning or replacing the pan gasket
Inspecting for signs of metal shavings or debris
Using a fluid exchange machine for a complete flush

In some cases, a drain-and-fill may only replace part of the fluid. A full fluid exchange replaces almost all of it, offering better protection, especially for older transmissions or those showing early signs of trouble.

5 Services to Combine With Your Next Oil Change

Mon, 28 Apr 2025 10:31:06 GMT

An oil change is one of the most essential and routine maintenance tasks for any vehicle—but it’s also the perfect opportunity to take care of other important services. Since your car is already in the shop and up on a lift, combining services can save you time, money, and future headaches. Here are five smart services to consider the next time you schedule an oil change.

1. Tire Rotation and Tread Check

Tire wear happens unevenly, especially if you drive frequently or carry varying loads. Rotating your tires every 5,000 to 7,500 miles helps them wear evenly, extending their lifespan and improving your vehicle's handling and braking. During this service, the technician can also inspect tread depth, sidewall condition, and check for embedded nails or other hazards.

Bundling a tire rotation with your oil change keeps you on schedule and ensures a safer, smoother ride.

2. Brake Inspection

You may not always notice gradual changes in braking performance, but your technician can. While your vehicle is being serviced, it's a good idea to have the brake pads, rotors, calipers, and fluid checked. Early signs of wear—like thinning pads or slight rotor grooves—can be addressed before they turn into costly repairs.

A quick brake check now could save you from needing an urgent (and expensive) brake job later.

3. Fluid Top-Offs and Condition Check

Your vehicle uses several fluids beyond just motor oil: coolant, brake fluid, power steering fluid, transmission fluid, and windshield washer fluid. Many of these systems are sealed, so low fluid levels or contamination could point to a leak or aging component.

Having your fluids checked and topped off during an oil change is efficient and helps avoid performance issues or warning lights in the near future.

4. Air Filter Replacement

Engine air filters prevent dust, debris, and bugs from entering your engine. When clogged, they can reduce performance and fuel economy. Replacing the filter is a quick and inexpensive service that improves airflow and helps your engine run more efficiently .

Since your hood is already open during an oil change, it’s a great time to inspect and replace the air filter if needed.

5. Battery Test and Terminal Cleaning

A weak battery may still start your car—for now. But corrosion, low voltage, or worn-out terminals can leave you stranded with no warning. Many shops offer a quick battery load test and visual inspection during other services.

If your battery is more than three years old or you’ve noticed slower starts, ask for a test and terminal cleaning during your oil change visit.

Bundling Services

Combining services during an oil change is about more than convenience—it’s a proactive approach to vehicle care. It allows the technicians to catch small problems early and helps you stick to a maintenance schedule without making multiple trips. Over time, this can extend your vehicle’s lifespan and reduce your overall repair costs.
